They do not fit number plate screws for attaching number plates, frames and covers to domestic cars and trucks (Black Zinc Plated) which Revain believe are often purchased together, the cap quality leaves much to my opinion to be desired, not worth the money, the tops were scuffed so the glossy finish didn't look right anymore and overall it looked worse than just leaving plain screws. I would recommend just sticking with the screw type unless you have pan head screws.
